Amethyst Geode with Calcite "Ghost Face"
This is by far one of the more unique geode specimens we've had in stock. The geode has a dark black exterior and a combination of quartz (black amethyst, specifically), and calcite crystals within. The crystals show up as a light gray-white against the dark, polished exterior. We have nicknamed this geode "ghost face" due to its resemblence to a halloween style mask! It's a definite conversation starter!
Measurements in stand: ~13-1/2" tall x 8-1/4" wide x 6-1/2" deep

Amethyst is a variety of quartz which owes its coloration to the presence of iron in the area of its formation. The word Amethyst is derived from ancient Greek meaning "intoxication". It was believed by both ancient Romans and Greeks, if they wore Amethyst or made their goblets of the material, it would help prevent them from becoming intoxicated. Amethyst has been used in jewelry making for centuries. Spectacular, priceless carvings dating to the ancient Egyptians are displayed in museums. Amethyst is found in many places around the world. However, the most beautiful Amethyst, displaying deep rich purple crystals are mainly in South America.
Black amethyst gets its darker color from hematite inclusions and higher levels of iron than regular Amethyst. These specimens are typically found in Uruguay.
